DETAILED DESCRIPTION

A typical data center includes different kinds of hardware, such as servers, racks, switches, and storage arrays, and software from low level management software to operating systems, infrastructure as a service (IaaS) (e.g., OpenStack), hypervisors, virtual networking applications, middleware, databases, and applications. The software and hardware components of datacenters have logical (e.g. topology) relationship consisting of a number of layers, including application, operating system (OS), virtual machine (VM), virtual switch, hypervisor, physical hardware (e.g., CPU, memory, disk), server, network interface card (NIC), physical network, and storage. Further, for data center operators, it can be quite challenging to get the right information from and interact with different management software for a number of reasons: (1) variety: different hardware/software has different management software; (2) complexity: information from different hardware/software is not well organized (e.g., into a unified model); and (3) interaction: the complex information is hard to display and navigate.

Traditional data center management software provides a dashboard that is not context-aware with too much information returned at one time. Accordingly, example embodiments of the present invention provide improved data center operations productivity via integration of wearable (i.e., smart) devices with backend information technology (IT) services by orchestrating existing IT services into a unified information model allowing for more efficient and context-aware information navigation.

FIG. 1 is a block diagram of a system 100 according to an example embodiment of the present invention. Example embodiments of the present invention provide a pluggable architecture to integrate with different kinds of data center management systems. The pluggable architecture enables the system 100 to pull information from and interact with these existing systems via a layered information model to model data center including a directed graph based on the hardware/software components and their logical connections. Human-machine interaction and presentation methods, such as gesture, voice, and augmented reality, then may be used to interact with and navigate the layered information model.

As illustrated in FIG. 1, the system 100 comprises a backend service 110 accessible via an application programming interface (API) 120 by a user (i.e., management) device 130 operating a data center operations application 135. The backend service 110 may comprise a layered information repository 140, an orchestration engine 150, and a data pull engine 160 having one or more plugins 165 ₁-165 _(N) (165 generally).

In certain embodiments, the data pull engine 160 may provide a pluggable architecture with, for example, a plugin 165 for each kind of IT management system in the datacenter. The plugins 165 may extract logical and physical datacenter component attributes into node type instances with other related information and build relationships between nodes. For example, the system 100 may include plugins 165 to retrieve datacenter component attributes from any layer of the datacenter, including inventory management applications 170 ₁ (i.e., both datacenter component inventor and warehouse stock inventory), IaaS management applications 170 ₂ (e.g., OpenStack® and VMware® vCenter Server®), datacenter monitoring applications 170 ₃ (EMC® SMARTS® and ViPR® SRM), and other data center services 170 ₄ (datacenter services, generally 170).

In certain embodiments, the orchestration engine 150 may follow pre-defined rules to organize datacenter attributes returned from data pull engine 160 and construct a full directed graph of the logical relationships of the hardware and software datacenter components and store the directed graph into the layered information repository 140 as the layered information model 145. The orchestration engine 150 also may periodically synchronize the layered information model 145 according to a current datacenter topology.

In certain embodiments, the layered information repository 140 may store a layered information model 145 comprising a directed graph consisting of datacenter nodes and edges. As understood in the art, a directed graph (or digraph) is an ordered pair D=(V, A) where V is a set whose elements are called nodes or vertices, and A is a set of ordered pairs of vertices called arcs, directed edges, or arrows. As understood in the art, a network node is a logical component of hardware/software having a data structure describing its attributes and operations. For example, a database node may have attributes like tables and connections and operations like start and stop. Therefore, an edge in a directed graph may represent a logical relationship between nodes. For example, in a topological relationship, an application running on an Ubuntu system may be represented by the edge between the application node and the operating system node. For common nodes, an abstract node type may be defined to describe a common component, like a web application or an operating system, and provide attributes and operations. Also new abstract node types may be defined based on system requirements.

In certain embodiments, the user device 130 may be a smartphone, a wearable device (such as Google G1ass™ or a smartwatch), or a traditional personal computer. The user device 130 may run a datacenter operation application 135, which may be tailored to the attributes of the user device 130 and to leverage the capabilities of the user device 130, to parse and input and communicate with the backend service 110 via the API 120 and present a result output by the backend service 110 to the user of the user device 130. The user device 130 may provide various types of input including gesture, voice, camera, and traditional human interface device inputs such as keyboard, mouse, and touchpad. The user device 130 may provide various types of output including voice or other audio response, augmented reality, haptic feedback, or any other type of visual response.

FIG. 2 is a block diagram of a datacenter 200 for management showing physical and logical relationships according to an example embodiment of the present invention. As illustrated, the datacenter 200 may include a plurality of hosts 275 ₁, 275 ₂ (275 generally) with each host running a hypervisor (not shown) managing a plurality of virtual machines 280 ₁₋₁, 280 ₁₋₂, 280 ₂₋₁, 280 ₂₋₂. One or more of the hosts 275 may be connected via a switch 285 to a storage system 290 providing a plurality of storage units (e.g., LUNS) 295 ₁, 295 ₂.

As illustrated in FIG. 2, an application 270 may be logically connected to a web server 283 running on a first VM 280 ₂₋₁ operating on a second host 275 ₂ in the datacenter 200. The web server 283 may have a logical connection to a backend database 282 operating on a second VM 280 ₁₋₁ operating on a first host 275 ₁ in the datacenter 200. The first host 275 ₁ may be physically connected to the storage system 290 via a switch 285 with the database having a logical connection to a first LUN 295 ₁ provided by the storage system 290.

FIG. 3 is a block diagram of a directed graph of the physical logical relationships in the datacenter of FIG. 2 according to an example embodiment of the present invention. As illustrated in FIG. 3, the directed graph may include nodes representing the application 270, the database 282, and the web server 283 (in an application layer), with the logical relationships among the application 270, the database 282, and the web server 283 being represented by a plurality of respective edges [270, 282], [270, 283], [282, 283]. As described above, the database 282 and the web server 283 may be running on respective VMs 280 ₁₋₁, 280 ₂₋₁, with those logical relationships represented by respective edges [282, 280 ₁₋₁ ], [283, 280 ₂₋₁], with the VMs 280 ₁₋₁, 280 ₂₋₁ running on respective hypervisors (not shown) running on respective hosts 275 ₁, 275 ₂ and the physical relationships between respective VMs 280 ₁₋₁, 280 ₂₋₁ and hosts 275 ₁, 275 ₂ being represented by respective edges [280 ₁₋₁, 275 ₁], [280 ₂₋₁, 275 ₂]. Moreover the physical connections between the first host 275 ₁, the switch 285, and the storage system 290 may be represented by respective edges [275 ₁, 285], [285, 290], with the logical relationship between the storage system 290 and the LUN 295 ₁ being represented by an edge [290, 295 ₁].

Referring to FIGS. 1, 2, and 3, in operation, the orchestration engine 150 may initialize the layered information repository 140 by triggering the data pull engine 160 to extract logical datacenter component attributes via the plugins 165 and the datacenter services 170 into node type instances. The orchestration engine 150 then may organize the datacenter attribute nodes returned from the data pull engine 160 into a full directed graph and store the directed graph into the layered information repository 140 as the layered information model 145. The orchestration engine 150 also may periodically perform these operations in the background to update the layered information model 145 according to observed changes to the datacenter topology.

A user, via the user device 130, may provide an input/request to the datacenter operation application 135 regarding an aspect of datacenter operation. The user device 130 may service the input/request, via the API 120, to the backend service 110 which may be handled by the orchestration engine 150. The orchestration engine 150 then may query the layered information repository 140 for results satisfying the input/request. The orchestration engine 150 then may return the results to the datacenter operation application 135 via the API 120 for presentation to the user via the user device 130.

In certain embodiments, the input/request from the user may be a command to perform an action on the datacenter via a datacenter service 170. Therefore, the output/command from the datacenter operation application 135 may be sent by the user device 130 via the API 120 to the backend service 110 and routed by the orchestration engine 150, according to the layered information repository, to the appropriate data pull engine 160 plugin 165. Accordingly, the system 100 may enable orchestration of existing IT services into a unified information model and provide improved datacenter operation productivity.

FIG. 4 is a screenshot of a display 400 of a user device according to an example embodiment of the present invention. FIG. 4 may be described in conjunction with FIG. 1. As shown in the screenshot, a rack 405 may house a plurality of blade servers 410 ₁, 410 ₂, 410 ₃ (410 generally). A datacenter operation application 135 may connect via an API 120 to a backend service 110 according to an example embodiment of the present invention.

The datacenter operation application 135 may use, for example, spatial recognition or other marks identifiable by the datacenter operation application to identify a particular blade server 410 ₁ and submit the identity of the particular blade server 410 ₁ to the orchestration engine 150 for identification in the layered information model 145 stored in the layered information repository 140. It should be understood that, in certain embodiments, the layered information model 145 may be built prior to the request for the datacenter operation application 135 or may be created “on the fly” as described above with respect to FIG. 1. As illustrated in FIG. 4, the layered information model 145 may store a directed graph representing the physical and logical relationships between various components in the datacenter, such as the rack, cabling, blade servers, drives, power supplies, memory, CPUs, NICs, hypervisors, and VMs.

The datacenter operation application 135 then may provide feedback to the user regarding attributes of the blade server 410 ₁. For example, as illustrated in FIG. 4, the datacenter operation application 135 may display gauges 150 ₁, 150 ₂, 150 ₃ showing blade server utilization metrics, such as memory, CPU, and network. Using the directed graph, the user then may navigate the datacenter (or, here, the rack), by, for example, navigating across the graph to another blade server 410 in the rack 405, navigating up the graph to the rack layer or datacenter layer, or navigating down the graph to the VM layer to view individual VM performance metrics.

Processing may be implemented in hardware, software, or a combination of the two. Processing may be implemented in computer programs executed on programmable computers/machines that each includes a processor, a storage medium or other article of manufacture that is readable by the processor (including volatile and non-volatile memory and/or storage elements), at least one input device, and one or more output devices. Program code may be applied to data entered using an input device to perform processing and to generate output information.

When the program code is loaded into and executed by a machine, such as the computer of FIG. 5, the machine becomes an apparatus for practicing the invention. When implemented on one or more general-purpose processors, the program code combines with such a processor to provide a unique apparatus that operates analogously to specific logic circuits. As such, a general purpose digital machine can be transformed into a special purpose digital machine.
